ZTTO MTB Eccentric QR Titanium Alloy Skewers TI Ultralight 9mm 5mm Quick Release 100 135 Hub 52g Lightweight Axle 9x100 10x135

The reviewer mentions the ZTTO skewers only once, briefly. They state they are swapping the bike's original heavy, rusty skewers for these 'nice lightweight titanium AliExpress ones.' They note these are the same skewers they had just taken off their hill climb bike to replace with even lighter ones, and they decided to install them on the Trek bike because they were lying around in their parts bin.
